Abstract

The hybrid composite materials have assumed a massive importance in aerospace industry, automotive construction and marine sector as a way to enhance the physical and mechanical performance. Glass, Kevlar and light weight carbon fiber are in rise. The goal of this study is an experimental and numerical investigation: natural frequency, mode shape and damping properties of hybrid composite plates consisting of alkaline treatment kenaf mat (300 g/m²) fiber in 5% of NaOH concentration for 48h and unidirectional carbon fibers. Three Hybrid Composites Plates (HC01, HC02 and HC03) of 4 ply had manufactured using hand lay-up process with different fiber orientation ([0/0]s, [0/90]s and [0/45]s), where the carbon fibers had used in the top and bottom. As results, the effects of kenaf orientation have affected considerably on the stiffness and dissipate energy considerably (HCP0 was highly by 16% as compared to HCP90). Besides, the appearance of combined mode shape (flexural and torsional) in the case of [0/45]s plate.

Keyphrases: Hand lay-up, Hybrid composite, Mode shape, damping, natural frequency
